AUTOMATIC WIRE-GUIDE FOR PAPER-MACHINES.

SPECIFICATION forming part of Letters Patent No. 260,356, dated July 4,1882.

' Application file d October 26, 1881. (No model.)

To all whom it may concern:

Be it known that I, THOMAS P.-BARRY, a citizen of the United States, anda resident of the town of Stillwater, in the county of Sara toga andState of New York, have invented certain new and useful Improvements inAuto matic Wire-Guides for Paper-Machines, ,of which the following is aspecification.

My invention relates to certain improvements in wire-guiding deviceswhereby wire aprons of the machine are guided as they are carriedforward.

It consists of the combination of devices hereinafter described andspecifically set forth.

The objects of my invention are to provide means by which the guide-rollcylinder which supports the wire apron is made to operate mechanismintermediate between the said guide-roll cylinder and guides at the sideedges of the wire apron, so that said guides will be automaticallyoperated to truly and properly guide the said wire apron in itsforward-move nicnt, .and also to provide means by which'an attendantwill be enabled to cause the-said wire'apron to be guided in its forwardmovef ment should certain parts of the automatic mechanism becomedisarranged or ontof order. I attain these objects by means of themechan.

ism illustrated in the accompanying drawings, in which similar lettersof reference, indicate like parts.

Figure'l represents a plan view of a section of a paper-making machineand my improved wire-guiding device attached. Fig. 2 is aside elevationof the guide-roll cylinder carrying the Wire to be guided and an endview'of my improved device. Fig. 3 is a front side elevation of thedevice. Fig. 4 is a rear side elevation of the same; and Fig. 5 is across-sectional view of the same, taken at line No.1 in

1. In the drawings, A A represent the frame 'of a paper-making machine,and B is a guideroller supporting the wire web or apron'-O,

' as it moves forward.

which myimproved device is intended to g'uide Secured to one of the sideportions, A, of the frame of the machine is the bed or way D,

- made preferably with a V-shaped form, as

shownin Fig. 5. Made with the said way, and extending outward and in alateral direction from the same, are brackets a a, which bracketssupport shaft 1), which is free to revolve in said shaft by a feather orspline, d, fixed in said shaft and working in a seat made inthe hub ofsaid ratchet-wheel.

F is a. bearing of shaft e of guide-roll cylinder or roller B, whichbearing is made solid with or attached to bracket H, which bracket ispivoted to shaft 1) by arms 9 g, and is supported by way or bed D, onwhich the lower foot ends of said bracket rests, as shown in Figs. 1, 3,4, and 5. Being thus pivoted to shaft 1) and supported by way or bed D,the said bracket H is adapted to be turned up from a horizontalposition, as shown in the several figures, to the position shown bydotted lines in Fig. 5.

The pivoting eye or bearing in arm 9 of bracket H is provided with ascrew-thread, which corresponds with the screw-thread of section 0 ofshaft 1), and said screw-threaded section works in said screw-threadedeye of arm 9, as shown in Figs; 1 and 3.

Mounted on the upper side of bracket H,and againstoradjacentto bearingFof guide-roll cylinder B, is housing I, in which freely works bar J,which bar is adapted to be nlovedin either direction transversely to thedirection of shaft 12. A notch, 17, Fig. 1, is made in the end of saidreciprocating barJ next to the end ofguideroll cylinder B and in itsside facing. "Secured to the shaft of said guide-roll cylinder, so as torevolve with the same, is cam-wheel K, formed by an annular flangearranged in oned'iree.

tion slightly oblique to the axis of guide-roll cylinder B, as shown inFig. 2. The said camwheel works in notch 12 of bar J and moves the saidbar alternatelyin opposite directions as guide-roll cylinder B isrevolved.

Pivoted to the end of reciprocating bar J,

opposite to its notched end, are dogs a a, Figs. 1 and3, which dogs areheld and drawn toward each other by spring s, Fig. 3, and engagerespectively with the teeth at m of wheel E, as shown in Figs. 1 and 3,accordingly as said wheel E is in situation for engagement with saiddogs, as will be hereinafter described.

Supported in arms 0 o, projecting from the way or bed D, isaverticalshaft, L. To the lower end of said shaft is secured crank 2, providedwith vertical arms q, Figs. 2, 3, and 4. Pivoted to the upper end ofsaid vertical arm q is a forked pitman, 1', which pitman is yoked to aloose collaror sleeve, t, on the hub of wheel E.

Secured to the vertical shaft L at its upper end is arm M, carrying aclamping device, consisting of upright stud N, provided with an oblongslot and set-screw. (Shown in Figs. 3 and 4.) Secured in said clampingdevice at one of its ends is the shitting-bar P, the opposite end ofwhich works freely in sleeve Q, supported by standard Q, attached to theframe of the machine, as shown in Figs. 1 and 2.

Secured to the shifting-bar P by clamping devices It R are guides T T,which guides are each composed of two rollers, u u, Figs. 1, 2, 3, and4, arranged and connected with plate a by being pivoted to ears madewith said plate, as shown in Fig. 4. The said guides thus composed areeach pivoted to their respective clamping devices R R, as indicated bydotted lines to in Fig. 4, and are each eapa ble of a swivelingmovement.

Secured to one endof shaftb is a hand-wheel, X, which may be operated ineither direction for shifting the bearings of guide-roll by hand whencircumstances require, as will be hereinafter described.

The mannerin which the several parts ofmy improved device operates is asfollows: The guides T T are set near to the side edges of the wire apronG, with their rollers u u at a distance from the same as themachine-tender may select. The guide-rollcylinder B revolves indirection of arrow No. l in Figs. 1 and 3, and carries the wire apron tobe guided in direction of arrow 2 in same figures. The cam K, attachedto the shaft or journal of guideroll cylinder 13, revolves with thesame, and works in the notch made in the reciprocating bar J, and causesthe said bar to be moved once in each direction ateach revolution ofsaid guide-roll cylinder and operate said bar, so as to carry the dogs an to a full movement back and return at each side of the ratchetwheel.The ratchet-wheel E being mounted loosely on shaft b, and held by itsfeather so as to turn with said shaft, is adapted to move longitudinallyon the same in either direction and between dogs at a. When the wireapron is moving forward uniformly and truly with its side edges instraight lines of direction the said dogs will be movedbackand forthwithout engaging with the teeth of said ratchet-wheel. When the wireapron 0 begins to shift or run from side A of the machine the off sideedge, 1, of the apron will crowd against the rollers u u of the guide T,when the shifting-bar P will draw armM in direction of arrow 4 and causecrank-arm p to move in direction of arrow 5, and through pitman randsleeve tmove ratchet-whecl E toward dog a, so that said dog will work inengagement with the teeth m of the same. As the revolution of guide-rollcylinder B is continued cam K will impart to bar J a reciprocatingmovement, by which the dogs a n will be moved back and forth, the dog abeing-out of engagement with the ratchetwheel, while the dog a will bein engagement with the teeth at of the same and at each return movementdraw on said teeth and cause the ratchet-wheel to be moved in directionof arrow 6, when the screw 0 on shaft b will be turned and cause bearingF to be shifted in direction of arrow 7. This shiftingof said hearingwill be attended bya gradual shifting also of bar J and its attacheddogs n n in the same direction, so that in a short time the dog a willbe out of engagement with the ratchet-wheel, while dog n will be throwninto engagement and will operate to turn the ratchet-wheelin an oppositedirection, and also operate the screw ot'shaft b to shift bearing F, andalso the said dogs, in direction opposite to arrow 7. v 7

It will be seen that the dog it operates to turn the ratchet-wheel whenit is drawn toward the wire apron, and moves the said ratchet-wheel indirection of arrow 6; also, that dog a operates to turn the saidratchetwheel when it is pushed back, and moves the ratchet-wheel in anopposite direction to that indicated by arrow 6. When the dogs areoperated back and forth, and at the same time free from engagement withthe teeth of the ratchet-wheel, the said ratchet-wheel will be idle, andthere will be no relative shifting of parts. When this idle condition ofparts exists the wire apron is running evenly and uniformly straightwithout its side edges exerting any great pressure on their respectiveguides T T, while when the side edge at guide Tbears against that guideitwill tend to throw the ratchet-wheel toward dog a at engagement withthe same, when the said dog, operating with teeth at, will graduallyshift the parts and cause the opposite operating-dog,n, to be carriedtoward teeth at of the ratchetwheel, while the dog a will be thrown outof engagement with teeth m. When the side edge of the wire apron pressesagainst guide T the said pressure will operate to slightly move arm M inopposite direction to arrow 4, and cause the crank-arm p to operatepitman 1' so as to shift the ratchet-wheel toward dog a and inengagement with the same, when the screw will be turned in an oppositedirection and carry bearing F and bar J and dogs n n in directionopposite to arrow 7, when dog n will be released from engagement withteeth mof the ratchet-wheel. These alternate movements or reversals ofaction of parts operate to hold the ratchet-wheel at nearly onesituation, and consequently it is made to resist the excessive pressureof the respective side edges of the wire apron, and be compelled to runwith its edges with comparatively uniform lines of movement.

' It should be understood that the wire apron does not run aroundguide-roll B, but is merely supported by the same, and is affected bythe slight shifting of its bearing F, in the manner above described.Should the dogs a n from any cause whatever become disarranged or out ofworking order, an attendant may, by moving the hand-wheel X in alternatedirections, readily direct the movement of the wire apron. This is agreat advantage, as the machine need not be purposely stopped but may becontinued to run until the web being made is completed or the usual timefor stoppage arrives. The support of the bearing F of the guide-rollcylinder directly over the way D removes all weight from shaft b, sothat said shaft is rendered easy to be turned.

In Fig. 5 dotted lines illustrate the manner in which the bearing F andits adjnnctive parts may be turned up. This adaptation of the saidbearing to be turned up, as shown, enables the operator to properly setthe bearing in line, as required, as he may, by turning the said bearingup without moving the shaft and then turning it down and moving theshaft, gradually adjust the bearing in one direction, while by turningthe said bearing up and at the same time moving the shaft in the samedirection, and then turning the bearing down while the shaft isheld fromtnrnin g, the said bearing will be shifted in an opposite direction. Itwill therefore be seen that by this means the said bearing will be setproperly.

I am aware that it is not new to construct paper-making machines with arule provided with plates and connected to a pair of levers, inconnection with a screw on which a double toothed wheel is secured, acurved lever carried by another lever, and a crank which imparts motionto the last-named lever. 1 am also aware that it is not new to providethe mechanism for guiding the wire cloths or belts of paper-makin gmachines with a crank-action for operating a double pawl toen gage bydraft or thrust a screw-nut ratchet-wheel to slide laterally a slide orpurchase; also, the combination, with the journal of a roller, of anadjustable crank to operate double-actin g pawls, which operate ineither direction a ratchetwheel; also, the combination of a bed-plateand a fixed screw-bolt with a screw-nut ratchetwheel to hold and operatea slide by the action of double pawls, which are operated bya crank. Itherefore do not claim such construct-ions.
